BEagle,
Thanks for your trying that out! To me that seemed logcal, but then these things aren't always logical.
Don Coyote et al,
After looking through several user manuals, it now seems that most if not all "next-generation" dual cordless phones (i.e., two handsets on the same base) now have the full "conference call" feature.
PPRuNe is incredible.....
Many thanks to all for your help!
Issue settled, now just need to go out tomorrow and get the new phones.

PS Herself will be pleased... she detested the old setup...
